Output Fields

Table 1 lists the output fields for the show firewall command. Output fields are listed in the approximate order in which they appear.

Table 1: show firewall Output Fields

Field Name	Field Description
Filter	Name of a filter that has been configured with the filter statement at the [edit firewall] hierarchy level. When an interface-specific filter is displayed, the name of the filter is followed by the full interface name and by either -i for an input filter or -o for an output filter. When dynamic filters are displayed, the name of the filter is followed by the full interface name and by either -in for an input filter or -out for an output filter. When a logical system–specific filter is displayed, the name of the filter is prefixed with two underscore (__) characters and the name of the logical system (for example, __ls1/filter1).
Counters	Display filter counter information: Name—Name of a filter counter that has been configured with the counter firewall filter action. Bytes—Number of bytes that match the filter term under which the counter action is specified. Packets—Number of packets that matched the filter term under which the counter action is specified.
Policers	Display policer information: Name—Name of policer. Packets—Number of packets that matched the filter term under which the policer action is specified. This is only the number of out-of-specification (out-of-spec) packet counts, not all packets policed by the policer.
